Producing food products is a demanding science. All of the industrial supplies and equipment which are utilized to manufacture foodstuff has to meet stringent requirements of quality and sanitation. With regards to industrial bearings, the food industry has to look at distinctive options. For example, would you want lubricating oil to contaminate food on the production line? Or what if bacteria were to grow in a machine's housing? Consumers will be put off to say the least. While industrial bearings have to be cautiously chosen with regards to cleanness and sanitation, they also have to be evaluated with regards to strength, hardness, durability, and cost.
It can take a special set of materials that may meet all of those criteria. The balls and rings themselves have to be made from high performance materials, regular iron won't meet the required FDA and United States Department of Agriculture standards. A common choice within industry is to utilize stainless steel balls and rings. They combine high tensile strength with good corrosion resistance and won't contaminate food. Nevertheless, they're probably the most expensive options, so other materials have been designed as balls as well. Plastic blends and may be utilized on their own or with stainless steel, particularly in plain or non rolled style industrial bearings.
Coated iron is a more affordable option as well. A chrome coating will improve the balls hardness and corrosion resistance and increase their duration. Zinc coatings are also common for improving corrosion resistance and preventing contamination. Industrial supplies, like machine housings, also face strict standards since they'll come into contact with food products throughout the production process. Generally, housings have to be smooth surfaces to facilitate cleaning and assist in preventing the buildup of germs and bacteria that may occur in rough or porous materials. Polished housings are extremely common, and there are also anti microbial coatings which might help protect industrial supplies and housings.
When considering materials of construction, housings are also typically stainless. A combination of strength, durability, and corrosion resistance is required. Industrial supplies in the food industry would be subjected to acidic and caustic wash downs and cleanings, along with oils along with other organic materials from the ingredients themselves. Again, more affordable options are available. Plastic and polymer mixtures are also chemically inert and will resist cleaning solutions and food products. Plastics can be created with high tensile strengths and smooth surfaces. Coated iron is also applicable for housings. A nickel or Teflon coating will go quite a distance to preventing corrosion and contamination. Using conventional oils and lubricants is clearly prohibited in the food processing industry. Lubricant contamination will spoil food, create a horrible taste, and is toxicity if consumed. Always use FDA and United States Department of Agriculture approved greases for the food industry.
